1) Ka mea huna o ka ʻili
Hoʻololi nui ʻia ka hoʻololi ʻana o ka waihoʻoluʻu ʻili e nā kumu ʻekolu.
1. ʻO ka maʻiʻo a me ka hāʻawi ʻana o nā puaʻa like ʻole i ka ʻili e pili ana i ka eumelanin: ʻo ia ka puaʻa nui e hoʻoholo ai i ka hohonu o ka waihoʻoluʻu ʻili, a ʻo kona ʻano ʻike e pili pono i ka ʻōlinolino o ka ʻili. I waena o ka poʻe ʻeleʻele, he nui nā melanin granules a hāʻawi nui ʻia; Ma waena o nā ʻAsia a me nā Caucasians, ʻoi aku ka liʻiliʻi a ʻoi aku ka hoʻopuehu. Pheomelanin: hāʻawi i ka ʻili i ka melemele a ʻulaʻula. ʻO kāna ʻike a me ka hāʻawi ʻana e hoʻoholo i ka leo mahana a me ka ʻoluʻolu o ka waihoʻoluʻu ʻili, no ka laʻana, ʻoi aku ka nui o ka melanin brown i ka poʻe ʻAsia. Carotenoids a me nā flavonoids: He mau puaʻa exogenous kēia i loaʻa mai i ka ʻai, e like me kā kāloti, paukena, a me nā meaʻai ʻē aʻe i waiwai i ka beta carotene, hiki ke hoʻohui i kahi melemele i ka ʻalani i ka ʻili.
2. ʻO ka mea i loko o ka hemoglobin i loko o ke koko o ka ʻili ua kapa ʻia ʻo Oxyhemoglobin: ʻO ka Oxyhemoglobin, he kala ʻulaʻula ʻulaʻula a nui i loko o ka ʻili, hiki ke hoʻolilo i ka ʻili i mea ʻoi aku ka ikaika a me ke olakino. Deoxyhemoglobin: He ʻulaʻula ʻeleʻele a poni paha ka hemoglobin non-oxygenated, a ke kiʻekiʻe kona ʻāpana i ke koko, ʻike ʻia ka ʻili.
3. Ma waho aʻe o nā mea ʻē aʻe, pili pū ka waihoʻoluʻu o ka ʻili e ke kahe koko, ke koʻikoʻi oxidative, nā pae hormone, a me nā mea pili i ke kaiapuni e like me ka ʻike UV. No ka laʻana, hoʻoulu ka radiation ultraviolet i nā melanocytes e hana i ka melanin hou aʻe e pale i ka ʻili mai ka pōʻino.
2) Ka mea huna o ka pigmentation
ʻO nā stains, i ʻike ʻia i ka lāʻau lapaʻau ʻo ka pigmentation lesions, kahi ʻano o ka pōʻeleʻele o ka ʻili. Hiki iā lākou ke ʻano like ʻole, ka nui, a me nā kala, a he ʻokoʻa ko lākou kumu.
Hiki ke hoʻokaʻawale ʻia nā stains i kēia mau ʻano:
ʻO Freckles: liʻiliʻi liʻiliʻi, wehewehe maikaʻi ʻia, nā kiko ʻulaʻula māmā e ʻike mua ʻia ma ka maka a me nā wahi ʻili ʻē aʻe i ʻike pinepine ʻia i ka lā.
Nā Lā a i ʻole nā makahiki: Nui kēia mau kiko, mai ka ʻeleʻele a ʻeleʻele, a ʻike pinepine ʻia ma ka maka, nā lima, a me nā wahi ʻē aʻe o ka poʻe waena a me ka poʻe ʻelemakule i ʻike ʻia i ka lā no ka manawa lōʻihi.
ʻO Melasma, i ʻike ʻia ʻo "nā wahi hāpai," ʻo ia ka mea maʻamau e like me nā ʻāpana ʻeleʻele ʻeleʻele symmetrical ma ka maka e pili ana i nā loli i nā pae hormone.
Post inflammatory hyperpigmentation (PIH): He pigmentation kēia i hana ʻia ma muli o ka hoʻonui ʻia ʻana o ka waihoʻoluʻu puaʻa ma hope o ka mumū, ʻike pinepine ʻia ma hope o ka hoʻōla ʻana o ka ʻili a i ʻole ka ʻili.
Hāʻawi nā kumu genetic i ka hoʻokumu ʻana o ka pigmentation: ʻO kekahi mau ʻano o ka pigmentation, e like me ka freckles, loaʻa kahi predisposition genetic ʻohana. Hōʻike ʻo Ultraviolet: ʻO ka radiation ultraviolet ke kumu nui o nā pigmentation like ʻole, ʻoi aku ka sunspots a me ka melasma. Nā kiʻekiʻe o ka hormone: ʻO ka hāpai ʻana, nā lāʻau hoʻopaʻapaʻa, a i ʻole nā maʻi endocrine hiki ke hoʻololi i nā pae hormone, e alakaʻi ana i ka ulu ʻana o ka melasma. ʻAha: ʻO kēlā me kēia kumu e hoʻonā ai i ka ʻili, e like me ka ʻeʻe, ka ʻeha, a i ʻole ka hopena maʻi, hiki ke hoʻoulu i ka pigmentation post inflammatory. Nā hopena ʻaoʻao o ka lāʻau: ʻO kekahi mau lāʻau lapaʻau, e like me kekahi mau lāʻau antimalarial a me nā lāʻau lapaʻau chemotherapy, hiki ke hoʻoneʻe i ka puaʻa. Ka waihoʻoluʻu o ka ʻili: ʻOi aku ka maʻalahi o ka poʻe me ka ʻili ʻeleʻele i ka pigmentation kiʻekiʻe.
